MECHANISM FOR CHANNELING, FEATHER-EDGING, AND ROUNDING MACHINES.

SPECIFICATION forming part of Letters Patent No. 618,564, dated January 31, 1899.

Application filed July 14, 1897. Serial No. 644,506. (No model.)

To all whom it may concern.-

Be it known that 1, WILLIAM E. FISCHER, of Boston, county of Suffolk, State of Massachusetts, have invented an Improvement in Power-Controlling Mechanism for Channeling,Feather-Edgin g, and Roundin g Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and numerals on the drawings representing like parts.

It has been and is now common to operate by hand machines of the class herein to be described, they containing a wheel to support the sole, a presser foot or roll to keep the sole on said wheel, and a knife or cutter to channel or feather-edge or round the tapsole while being fed between said wheel on the one side and the said roll or foot, or both, on the other side.

The object of the invention to be herein described is to actuate this class of machines by power and to control the application of the power to run the machine by or through the action of the edge of the sole being channeled or feather-edged or a sole-shaped pattern to which a tap-sole to be rounded is attached against an auxiliary edge-gage.

I have provided a machine of the class described with a continuously-moving drivingpulley, and cooperating with the pulley I have combined a friction device which is acted upon to effect the clutching of the friction parts with the continuously-rotating drivingpulley to actuate the feeding mechanism for the Work to be done only when the edge of said work or the edge of the pattern carrying it occupies a predetermined position in the machine and between the wheel and roll referred to.

The machine herein to be described has the usual edge-gage, and at one side of the edgegage I have located an auxiliary edge-gage, it being movable horizontally with relation to'the usual edge-gage, so that so long as the edge of the sole or the pattern referred to is kept against said auxiliary edge-gage the driving friction is kept operatively engaged; but should the operator let the edge of the sole or the pattern referred to retire from said auxiliary gage, so as not to h old it pressed and close the'friction, then the motion of the said wheel and roll will immediately stop.

Figure 1, in side elevation, represents a sufficient portion of a machine of the class described with my improvements added to enable myinvention to be understood. Fig. 2 is a top or plan View of Fig. 1. Fig. 3 is a partial front elevation chiefly to show the wheel, roll, and parts between them. Fig. 4 is asectional detail to the left of the dotted line m, Fig. 1. Fig. 5 shows part of a knife or cutter for channeling. Fig. 6 is a sectional detail taken through the wheel on which the work rests, chiefly to show the shafts. Fig. 7 is a section to the right of the dotted line as, Fig. 1. Fig. 8 is a section in the dotted line Fig. 7. Fig. 9 is a section to the right of the dotted line m Fig. 8. Fig. 10 shows a feather-edging knife.

The framework may consist of a base A and suitable uprights A, and one of these uprights is shown as having pivoted upon it at A a suitable arm, as A carrying a shaft A, provided with a roll A and a pinion A, the free end of said arm having attached to it by a screw a a presser-foot A and bya screw a a knife or blade ct, the knife (shown detached in Fig. 5) being shaped to cut a channel in the top of the sole near its edge, and the edgegage a secured to the top of the upright A by a screw a (see Fig. 1,) and the rod A and spring A are and may be all as usual in this class of machine.

The roll A is herein shown as smooth for the reason that it is to act on the hair side of the work, and the work (a sole) is fed through the machine by, as herein shown, a toothed wheel composed of two parts B B, the one, B, being on a hollow shaft B provided with a gear B which is engaged and driven by a pinion f, to be described, forming part of the friction, the said gear being in mesh with the pinion A on and rotating the shaft A. The part B of the wheel referred to is fast on the end of a shaft B suitably jointed to the right-hand end of the hollow shaft, substantially as in my Patent No; 588,970, dated August 31, 1897, so as to be rotated with it, yet be free to be moved inside said shaft, so as to position correctly the periphery of the part B with relation to the part B, the outer or left-hand end of said shaft 13 having, as shown, loose on it a box B which may rise to be adjusted up or down in a fork of the upright B by a suitable screw. Instead of this particular wheel I may use any other wheel commonly employed in the class of machines referred to on which the work may rest, and in practice that wheel which acts on the flesh side of the piece of leather being cut or toothed.

To feather-edge instead of channel a sole, the knife will be of a shape substantially as shown in Fig. 10.

I will now particularly describe the improvements which I have added to this class of machine.

The bed-plate A has erected upon it a suitable bearing C, on the top of which I have mounted a lever C. One end of this lever has connected to it a bar C provided at its end with an auxiliary gage C The bar is herein shown as jointed at O to a tipping rest G which may be supported by a spring 0, the spring yielding when the nut O is turned more or less onto the threaded end 0 of said rest, extended loosely through a large or rounded hole in an ear 0. The bar C is also shown as jointed at 2 to a rest I), mounted in a suitable ear I) of the frame, the connectlon being such that the rest I) may be vibrated somewhat in said ear as the bar is moved backward and forward longitudinally or the gage at its end is moved backwardly with relation to the face of the regular edge-gage. By adjusting the rest I) by or through the nuts b and b the position of the auxiliary edgegage with relation to the side of the usual edge-gage may be altered to adapt the position of the auxiliary gage to the particular shape or curvature of the sole being acted upon. The lever C has attached to its other end a connecting-rod d, which is extended, as shown, through a hole in a lever d, forming part of a clamping device, said lever being pivoted at d and having, preferably, an attached friction block or face (1 The said lever may be acted upon by a spring 61*, connected to a stud (Z to normally hold said friction-face out of contact with a plate or disk d, having a hub (1 loosely mounted on a hub e of the power-driven driving-pulley e fixed on a short shaft diresting at its opposite ends in suitable bearings (Z (1 The hub 61 has two slots 5, which receive pins 6, projected from one side of a collar f, mounted loosely on said shaft (1 at the opposite side of said driving-pulley, the said pins projecting through spaces of said pulley to enter said notches. These pins are joined to suitable springs f, fastened at their other ends to projections of the driving-pulley. This collar, at its sides opposite these pins and located between them, has other pins 7, which serve as pivots for two like links f shaped at their outer ends to act against shoes f pivoted at f on the said driving-pulley and provided with suitable friction-faces f 5 to bear against the periphery of a chambered pulley f loose on the shaft (Z said pulley having at its hollow hub a suitable pinion f which in the rotation of said pulley engages the gear 13 and rotates the shafts referred to of the machine.

The link (Z has at its end a head g, which acts against one side of the friction-clamp d, and said link is surrounded by a spring r, the pressure of which is regulated by an adj ustable nut 9 and said spring acts against the opposite side of said clamp. By turning the nut g on the link (Z I may adjust the position of the face of the auxiliary guide with relation to the face of the edge-gage.

In Fig. 2 it will be supposed that the driving-pulley is being rotated continuously, and with it rotates the shoe and also the frictiondisk d and collar f; but the friction-faces of said shoes do not press sufficiently hard upon the periphery of the chambered loose pulley f carrying the gear fflwhich is used to drive the machine, and consequently the machine parts stand at rest. To start the machine, the edge of the leather to be acted upona sole usually of some form or a pattern, as has been referred to, carrying a sole-will act against the face of the auxiliary edge-gage on its way to the usual edge-gage, and the pressure of said sole or pattern against said auxiliary gage will force it in this instance to the right,viewing Figs. 1 and 2,which motion will cause the link d to be drawn in the direction of the arrow, Fig. 2, which will cause the clamp to be forced with sufficient pressure to temporarily check the rotation of the disk d in unison with the driving-pulley, the checking of said disk causing the pins 6, locked in notches of the hub of the disk, to be checked in their rotation, and the checking of this disk also checks the rotation of the collar, causing the latter to draw upon the links f in opposition to the springs f, and said links when drawn upon force the shoes,with their friction-faces, firmly against the periphery of the loose pulley f and thereafter in the continued further rotation of the driving-pulley the shoes connected with it and forced in contact with the periphery of the pulley f will be rotated substantially in unison with the driving-pulley, and the pinion f in mesh with the gear 13'', will effect the rotation of the shaft 13*, and consequently, as described, of the entire machine, and this rotation will be continued so long as the edge of the sole or the pattern described act properly upon the auxiliary gage; but should the operator in handling the sole move it away from the said gage improperly, so as to free the said gage from pressure, then immediately the friction between the friction-face d of the clamp d and the friction-disk d is so far loosened that said disk immediately, under the bidding of the springs f, catches up with the speed of rotation of the driving-pulley and immediately turns the collar f in the direction to release the shoes from their frictional contact with the pulley f, and the machine immediately stops.

\Vhen the machine is in operation, the friction-disk is revolving, it will be understood, all the time, but it is held back somewhat by the clamp referred to sufliciently to, through the collar f and the links f draw the shoes against the periphery of the friction-pulley.

In rounding a piece of leather for a tap-sole the piece of leather will be suitably secured in usual-manner to a pattern shaped to represent the shape desired for the tapped sole, and this pattern will rest on the wheel carried by the shaft B of whatever form, and the auxiliary edge-gage, by or through rotation of the nut 0" will be adjusted vertically, so that it will act against the edge of the pattern, leaving the edge of the piece of leather to be rounded to be cut to shape projecting a little beyond the edge of the pattern, so that as said pattern is turned as it is being fed through between the wheels of the roll referred to the said edge will be acted upon by the perpendicular edge of the plate, such as is commonly employed for sole-rounding.

A sole itself, out to shape, may act as a pattern.

I have herein described myinvention as applicable to several different machines, each one performing a different class of work; but to adapt a machine to one or the other of these different things requires but a trivial change, changes well known; but my improvement in means for automatically driving, starting, and stopping the well-known parts of these machines may be easily and readily applied to any one of these machines, and it is equally valuable in all.

Believing myself to be the first to automatically drive by power a machine of the class described, I desire it to be understood that this invention is not limited to the exact means herein shown-that is, to the exact construction herein described of the friction parts cooperating with the constantly-rotatin g driving-pulleybut that said friction devices may be variously modified without departing from my invention; and so, also, this invention is not limited to the exact shape shown of the auxiliary edge-gage or the manner in which it is connected with and to operate the friction devices.

The lever O, the link d, and the clamp d may be designated as the friction-actuator, it being under the control of the auxiliary gage, and this auxiliary gage is employed herein chiefly as a starting means for causing the engagement of the friction device,of whatever form, with a moving part of the continuously-rotating driving-pulley. I believe I am the first to ever use any gage of this sort for such purpose, and I therefore intend herein to claim the same very broadly.

I have herein shown a wheel and a roll between which the material to be acted uponis held and fed; butin this class of machine there are other varieties of feed which engage and release the work intermittingly, and this invention is not, therefore, limited to the particular feeding mechanism herein shown, I choosing to designate the Wheel and roll as a feeding mechanism in the claims.

The edge-gage a is considered an essential element in this invention; but the feeding mechanism maybe changed for any usual kind common to the class of machines referred to.

Having described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In a machine of the class described, an auxiliary power-controlling edge -gage, combined with a main edge-gage, to operate, substantially as described.

2. In a machine of the class described, an auxiliary power-controlling edge-gage, and feeding mechanism adapted to be-started and stopped by or through said auxiliary edgegage, combined with a main edge-gage, substantially as described.

3. Inamachine of the class described, feed= ing mechanism to move the material, an edgegage to guide the edge of the material passing between said feeding mechanism, combined with an auxiliary edge-gage against which the edge of the material may be borne on its way to the main edge-gage, and devices operated by said auxiliary edge-gage to start and keep the feeding mechanism in motion so long as the material being taken between the feeding mechanism is kept pressed against the said auxiliary ed ge-gage, substantially as described.

I. In a machine of the class described, feeding mechanism, an edge-gage, a continuouslyrotating pulley, a cooperating friction device adapted to be engaged with the said continuously-operating pulley to actuate the feeding mechanism, combined with an auxiliary edgegage, the change of position of which by or through the edge of the material passing be tween the feeding means governs the clutching or unclutching of the friction device with relation to the continuously-rotatin g drivingpulley, to thus start or stop the machine by or through the position of the material acting on the face of said auxiliary gage, substantially as described.

5. In a machine of the class described, the following instrumentalities, viz: a continuously-rotating driving-pulley, a friction device having a pinion, friction controlling means to effect the engagement of the friction device and the continuouslyrotating pulley, an edge-gage and feeding mechanism, combined with an auxiliary gage adapted to be acted upon by the material between said feeding mechanism to actuate the frictioncontrolling means and start and continue the operation of the feeding means, substantially as described.
